Never "take a dump" :) Capturing a hang dump with ADPlus when you are experiencing your issue will allow you to determine exactly whats going on in terms of executing threads, objects on the heap, etc. You would analyze the dump using WinDbg (I'm making the assumption that you're not familiar with these tools.) http://ayende.com/3303/how-do-you-track-that#comment8http://ayende.com/3303/how-do-you-track-that#comment8Tue, 06 May 2008 03:08:08 GMTAlex Simkin commented on How do you track that?@Yossi "Try take a dump when the process is stuck..."

If yes, take a look at the connection pools on the proxies. It _might_ have to do something with it. http://ayende.com/3303/how-do-you-track-that#comment6http://ayende.com/3303/how-do-you-track-that#comment6Mon, 05 May 2008 19:40:55 GMTYossi commented on How do you track that?Try take a dump when the process is stuck, maybe it would shed some light on what is going on then.. http://ayende.com/3303/how-do-you-track-that#comment5http://ayende.com/3303/how-do-you-track-that#comment5Mon, 05 May 2008 19:38:58 GMTAyende Rahien commented on How do you track that?James, Yes, I remember that.

If so, maybe you're hitting the half-open limit (assuming a client OS). Event logs with 4226? http://ayende.com/3303/how-do-you-track-that#comment1http://ayende.com/3303/how-do-you-track-that#comment1Mon, 05 May 2008 13:05:55 GMT
